  1. Strangely my nearest Stihl dealer has stopped stocking the Ultra. I have been given a bottle of Castrol power1, it is rated jaso FD so should be good enough. It is also red which I find far easier to see when pouring mix than the green/blue, it is a reassurance that I have the right stuff when filling. Generally I keep mix in red containers and neat in green but mistakes happen.
  2. Yup, me too, present most days
  3. I have the aldi ferrex version, cost 20 quid and I already had the battery and charger from my cheap drill and grinder. With the football inflator nozzle it is okay for air filters and basic blowing crud off a saw in the field. A bit pedestrian as the nozzle-airflow combination limits it to 11psi in use (it maxes out at 36psi anyway) and I only use it a minute or so at a time. It does car and bike tyres but I wouldn't attempt it on a tractor tyre.
  4. I started out in establishment in 1974 and gradually did a bit of arb and harvesting. From October 87 I was almost exclusively harvesting on my own account till 2009 when I moved to railway and yard work for a firm, I have been retired now 7 years but occasionally help out on small woodland work. A 6 hour day nearly finishes me off now, felling diseased ash.
  5. Fascinating, we don't have much hilly ground here though I did work with a skyline in South Wales. I have only seen videos of machines being lowered down steep slopes by a remote controlled winch. Costs must be horrendous. PS is there then a secondary extraction to where a lorry can get?
  6. Please would you explain the working method here? It looks like the trees have been machine processed and the forwarder then descends on the brash mat extracting a single bay of produce. What is the produce, all pulp? as there doesn't seem to be an assortment.
  7. Found in the potting shed at SY?
  8. Big place, how big a bar? I have a Jonsered 920 with 22" bar which I repaired and the lady didn't want back, seems to run okay but a beast to start and I'm sometimes down to Petersfield Not sure of the bar mounts but have an unused husky 25" 501-60-31-01 bar that should fit. I may even have an old chain.
  9. He's cut my reading time here by 80%, not sure whether that's good or bad.
  10. Just a follow up; The dead one, riddled with holes fell across the path, I wish I had taken a photo of the tree back then for context. The remains of the fruiting body from a year ago are centre bottom of the picture
  11. More likely spruce regen removal as non native on a Caledonian site but am interested in the real answer
  12. I wonder if @lurkalot has come across one of these?
  13. May be https://www.rhs.org.uk/disease/brown-rot I have it on my old apple and it has ruined the tree over several years
  14. Was it the schizophrenia?
  15. Same era certificate as mine and I refreshed it by doing the windblown then chainsaw from MEWP and it all got updated on the system, my last refresher was 8 years ago now so not acceptable to some firms without a further refresh.
  16. If the scrap price is still dictated by China's demand it may take a while, with deflation there cutting output and their domestic demand down.
  17. @adw is far more knowledgable than I but my take is the safe upper limit is 12000rpm and the rev limiter will prevent it going more but the best performance is at 9000rpm. As the rev limiter will cut in you will have to richen it so 4 stroking occurs below 12000rpm because if it is weak the rev limiter will prevent the revs going higher. Personally I find it difficult to tune these rev limited engines on things like hedge cutters, pole saws etc., so a few hints from the experts wouldn't be amiss.
  18. ...and they really dislike wire rope, apparently it wraps round the shredder and clogs it up
  19. The husky brochure says max power at 9k rpm, the thing is does it have a rev limiting coil? One for @adw perhaps We normally tune 2t motors to rev limit by 4 stroking at the maximum high speed, say about 13k rpm for a 50cc engine but it develops it full power at 8-9k rpm. If rev limited it cannot be tuned this way.
  20. Well given time I guess most bits of the earth get subducted to the core where metals will get recycled and we already know a few ways to get to mass human extinction even before Gaia takes a hand, mind it does look like she has already started. I like this one as it seems to simply cause the soot particles to agglomerate and stick to the chimney rather than needing frequent cleaning. It is the same, acceptable wattage as the last one I looked at but that cost £1800 plus fitting. It does still require access to the chimney top which will make annual sweeping a problem. Any idea of the cost? I looked at making one from an old microwave but it got a bit beyond me.
  21. Of course it is sustainable as long as the wood you burn is replenished by other trees growing. I burn arb waste that comes from leafy mansion gardens, there is no shortage of trees growing in large gardens. It makes no difference whether the wood is burned well or badly, producing smoke at sooty particles, they all end up being dealt with by the same mechanisms that have absorbed smoke from wild fires for millennia. Yes a poorly managed fire will produce more particulates than a good one but that has nothing to do with sustainability.
  22. Yes that's my view, he is a clever man.
  23. It remains sustainable even if those things are not right. The issue about domestic wood burning is one of people's heath. With particulates being identified as a problem to lungs, and 70% of them in the implicated PM2.5 class coming from some form of combustion, those from woodburning were bound to come to the fore as coal burning dwindled, stubble burning was banned, garden bonfires deprecated and engines fitted with DPFs, addblue and catalysts.
  24. The mills I was supplying 30 years ago would be mostly cutting fencing and things like pallet boards, most building material was imported. The best bits would make posts and arris rails with slats coming from side boards. Smaller diameter bars would also produce slats and these would go down to 6" under bark. The rest down to 2" or 3" would go for pulp or chip but these would seldom cover their cost of harvesting. By £10/m3 on out turn I meant I would pay for the sawlogs that left the site but would take the smaller wood for free, not pay up front on a standing measure. There is a catch here for the unwary land owner and I have had to clear up the mess where a contractor had agreed a high price for the thinning on out turn but only ripped out the sawlogs leaving a tangle of un debranched lengths of 8" tops as a tangled mess .
  25. As does the OP's nickname suggest the eastern end of the Med.
